Node JS Find all element's attr

I would like to find each element's id but I "each" doesnt work (there is no metode each...) How can I return each element's ID?

   var libxmljs = require("libxmljs");
 var xml = ('/SomePath/filexmlxml');
   var xmlDoc2 = libxmljs.parseXmlString(xmlStr);
 fs.readFile(__dirname + '/filexml.xml', function (err, data) {


     var xmlStr = data.toString();
var id = xmlDoc2.get('Objects').get('Object').attr('id').value(); // It works and get the first element id = 'Title 1'


     xmlDoc2.get('Objects').get('Object').each(function () {
         var whatid = xmlDoc2.get('Objects').get('Object').attr('id').value();
         console.log('wasd: ' + whatid);  // Doesnt work - because of each.
     })  
 console.log('idss: ' + id); here I can see the only first's element's ID.

javascript
jquery
node.js

xmlDoc2.get('Objects') will return a Node object. It doesn't have a each method. You can use prevSibling, nextSibling methods to traverse the siblings of the nodes.

Or even better use childNodes on the element.

var children = xmlDoc2.get('Objects').childNodes();

children.forEach(function (child) {
  var whatid = child.get('Object').attr('id').value();
  console.log('wasd: ' + whatid);
});
